Transport preferred route types
A transport preferred route can exist without a specified transport preferred route type. This implies that the preferred route applies to all trucks (not including B -Triple road trains).
A link being part of different preferred routes causes publishing of multiple preferred route conditions.
Type = 1 - STAA Route applies when the preferred route belongs to the highway network as defined by the Surface Transportation Assistance Act in the U.S.
Type = 2 - TD Route applies when the preferred route is part of a state designated highway network for trucks in the U.S.
Type = 15 & 16 - The functional class overrides apply when there is a restriction for trucks for a small section of the FUNCTIONAL_CLASS = 1 or FUNCTIONAL_CLASS = 2 road. These are published based on local knowledge. Example: The left side of the “Drechtunnel†in Netherlands is a FUNCTIONAL_CLASS = 1 road and restricted to trucks. Trucks should take the right side of the tunnel, which is a FUNCTIONAL_CLASS = 3 road, which route planning would often not consider for long distance transport routes.
Type = 17 applies only for routes that allow articulated vehicles with a second semi-trailer attached to the rear of the first semitrailer by means of a turntable. Single semi-trailers and delivery vehicles that adhere to the same length, height, and width restrictions may use BDouble routes. Generally, the vehicle must adhere to the following specifications to traverse the B-Double Routes:
- Height equal or less than 4.6 metres
- Width equal or less than 2.5 metres
- Length equal or less than 26 metres (27.5 Metres in Western Australia)
- Weight equal or less than 68 tons
- No permit has to traverse the B-Double Route if the vehicle complies with the preceding specifications. Published BDouble routes don't include Higher Mass Limit (HML) roads requiring a permit, and Road Trains.
Type = 18 applies only for routes that allow articulated vehicles with a second and third semi-trailer attached to the rear of the first semi-trailer, by means of a turntable. Single semi-trailers and delivery vehicles that comply to the same length, height, and width restrictions may use B-Triple routes. The vehicle specifications differ per state and are available on the regional transport websites.
